Example Analysis
Consider \(h(x) = \sqrt{3-x}\).
First we evaluate at \(x=-4\). 
We see that \(h(-4)=\sqrt{7}\). We can also evaluate
approximately in R.
h <- function(x){sqrt(3-x)}
h(-4)## [1] 2.645751We also evaluate \(h\) at \(x=5\). We see in the work below that the
value \(h(5)\) is undefined. 
The warning we see in R is because \(h(5)\) is an undefined value.
h(5)## Warning in sqrt(3 - x): NaNs produced## [1] NaN
